Description
The field of gravitational-wave cosmology has picked up steam in recent years due to important observations done by LIGO-VIRGO-KAGRA, such as GW150914 and GW170817. However, the absence of a galaxy catalog that is optimized for the purpose of resolving the positions of gravitational-wave sources has been a known issue. This work is part of the newly proposed survey, Sirenas, and aims to create galaxy samples uniformly with similar absolute luminosities to those 20-30 events of interest. To achieve this goal, we utilized a model faint blue galaxy and the luminosity distances to each event to determine our depth thresholds in absolute luminosity space. This work contributed to calculate and optimize the survey exposure times in each region to ensure that we achieved the target depths in all areas while optimizing the distribution of telescope time across all targets.
